SAFETY FEEDING DEVICE FORULOTHES WRINGERS.

Application filed- April 26, 1924. Serial No. 709,107.

Power operated clothes wringers have attained great popularity inhousehold laundries, and are now in general use. Feeding the fabricsbetween the compression rolls of such wringers is a very particularoperation and is frequently attended with injury to the fingers and handof the operator, due to being caught and drawn between the rolls,despite her most watchful care. i

The purpose of thepresent invention is the production of a feedingdevice for attachment to clothes wringers which will obviate theliability of the fingers of the operator being caught between the rolls,such feeding device being so-formed as to recelve the fabric and carryitto a point where it Will have frictional engagement with the rolls andbe drawn between them in the rotation of the latter. i The feedingdevice is embodied in a pivoted bar which is provided on its" forwardside with an elongated Wedge-shaped por tion, for entering the fabricbetween the rollers, and on its tapering sldcs with fixed protuberanceswhich latter are designed to support the fabric somewhat clear'ofthebar, so

that the fabric may be drawn between the rolls without dragging, thusgreatly facilitating'the movement-of the wet fabric over the bar withoutmaterial frictional resistance. Also it isthe function of the saidprotuberances, by engagement with the rolls, to restrict the movement ofthe wedge-shaped portion-into the space between the rolls.

The novel features of the invention will now be particularly described,and then pointed out in the appended claims.

In the consideration of this specification, reference is to be had tothe accompanying drawing which shows a simple constructional form inwhich my invention has been embodied. In such drawing:

plane which extends between the rolls of the wringer, and showing themanner of the attachment of my improved safety feeding device to theframe, the latter being transversely sectioned. I v

Fig. 2 is a vertical sectional view, enlarged, on the line 22, Fig. 1,looking in the direction of the arrows, and showing the manner in whichmy improved device operates.

Fig. 3 is a view in front elevation of the central section of the barembodied in the construction of my feeding device, and showingthe'wedge-shaped formation of the fabric feeding element, together withthe arrangement ofthe fixed protuberances on the tapering sides thereofwhich provide a clearance between the bar and the fabric restingthereon. v i In the drawing, the numerals 1O and'll indicate thestandards or a clothes wringing machine, in which standards the shafts'12 and 13-of the rolls 14: and 15, are journalled in themanner usual toconstructions of this kind. v I

A bracket 16 is attached tothe standard 10, such bracket receiving andsupporting pivotally one end of a feeding bar 17 the which is 'adaptedtoenter theopen space existing at the front side of the rolls and in theplane of their peripheral contact. In

the movement of the bar 17 toward the'roll's,

the wedge-shaped projection 19 is designed to penetrate the said openspace to an extent I that the tapering sides of the wedge will lieclosely adjacent the surfaces of, the rolls, but not in contacttherewith, so that the said wedge 1 cannot, accidentally or otherwise,exert a separating action upon the said rolls.

I achieve this restriction in the forward movement of the bar 17 by theprovision upon the bar of means for engaging the rolls at points remotefrom the line of their Figure 1 is a plan view in the horizontal themanner hereinbefore described, they have the further important functionbf su orting the fabric clear of contact with the sides of the wedge, sothat the wet fabric, when grasped'by the rolls, may be drawn off the barwithout drag 'ing over the sides thereof. Thus, the feeding ihove'iiintthrough the rolls is effected withoutimposing delicate fabrics to anyunusual strains, so that danr age thereto is avoided. v

The bar 17 with the fixed, rounded pro-1 tuberances 20 is cast as asingle piece, and

machining thereof for the reception of other adjunctive' parts isobviated. Preferably,

' the castingis ofalrminuni, but may be of any suitable material. It isadvantageous that itbenon-corrosive. In the interest of lightness, 1cast the wedge-shaped section with hollow rear portion, as indicated at21; i construction very economical in cost, and nay easily be attachedto any exist; ing machine.

Inoperation, the rolls are set in motion, and the bar 17 is swungoutwardly from the rolls by one handof the operator.- The wet fabricfrom the tubis then passed vertically into the widened space between therolls and the bar, laid overthe latter as thehar is moved toward therolls. a When the-fabric contacts with-the rolls under the pressureexerted the wedge-shaped portion of the bar, the frictional engagement.of the rolls with the fabric will draw the latter from the banana passit through the rolls, whereby the moistureis expressed from the fabric.

The Wet fabric will not cling to or drag over the sides of thewedgeshaped portion of the bar, for the fined protuberances 20 create aclearance which facilitates the movement of the fabric; The fingers ofthe operator are never near the rolls, and consequently liability to ijm-y r warded; i

Having thus described my invention, What I claim and desire to secure byLetters Pateiit of the Unitdstates, is:

1. As a new article of manufacture, a safety feeding device for clotheswringers constitutedas abar provided with means for pivotally supportingit at one end, and l'rand-engagingmeansat the other, whereby the saidbar may: be swung in a horizontal plane upon itspivotal support, thesaid bar being provided upon its forward side with a wedge-shapedportion, for entering the fabric between; the rollers, and the taperingsidesjof which wedge-shaped portion are provided with finedprotuberance-s, which latter support thefabric clear of thewedgeshapedport-ion; to facilitate its passage thereoverpandalso preventengagement of the wedge-sha ed portion with the rollers.

,2. Asafl new article of manufacture, a safetyfeeding device, forclothes wringers constituted as a bar provided with means for pivotallysupporting it at oneend, Whereby the said bar maybe swung in'a horizon-,tal plane upon its pivotal support, the said bar being provided upon itsforward side With a wedge-shaped portion, for entering the fabricbetween the rollers,an'(l the tapering sides ofwhichwedge shaped portionare provided with fixed H protuberances, which latter support the'fabricclear of thewedgeshaped portionto facilitate itspassage thereover,and'alsoprevent engagement of the wedge-shaped portion with the rollers.

In testimony whereof, Ihhave-signed my name atMilwaukee, this 21st dayof April,
